Abstract (en)
[origin: EP0855671A2] Present invention relates to an image processing method and apparatus, and image forming apparatus for inputting multivalued image data having a resolution e.g., 300 x 300 dpi, converting the resolution of the data to a higher resolution e.g., 600 x 1200 dpi and forming an image. In a memory, pattern data corresponding to image data of a predetermined color is stored in advance. When color data, image data (code) and data corresponding to an image forming position are inputted to the memory as an address, the memory outputs pattern data stored in the address. By selectively outputting the pattern data read out of the memory in accordance with the forming position, color image data where resolution has been converted is outputted, whereby forming an image. <IMAGE>
